Using clues left by his would-be assassin, Jack follows a trail that leads through France and Switzerland to Rostock, a shadowy security firm based in Germany. Jack knows its head, Jurgen Rostock, from a previous operation - one that has apparently drawn the man's fury.

Without the resources of The Campus - the elite agency from which he is on a leave-of-absence - but with the help of an investigative journalist, Jack embarks on his own secret campaign to uncover the truth about Rostock. And what he finds is that they are up to something both big and very, very bad.
